To connect the control head to ignition power:
1. Use a multimeter to determine which source provides power when the vehicle
key is in the ignition position.
2. Connect the yellow lead from the control head to the switched side of the
vehicle ignition harness. Extend the lead with 22 AWG leads or thicker.
3. Connect the red lead from the control head to a co12 Vdc from
the battery. Do not splice the red and yellow leads to the power leads for
accessories. Extend the lead with 22 AWG leads or thicker.
4. Connect the black lead from the control head to negative ground. Extend the
lead with 22 AWG leads or thicker.
5. Insulate spliced leads with twist-on wire connectors. Fold and seal unused
leads. Use wire ties and hold-downs for strain relief.
Connecting the Federal Signal Microphone (P/N 258B8577-03)
The microphone provides high quality voice reproduction in for public address
over the siren speakers. The microphone push-to-talk switch overrides all siren
functions, except radio rebroadcast, for instant PA use. The microphone connection
is not required for the siren to operate properly.
To attach the microphone cable to the control head, insert the modular telephone-
type plug in the microphone jack until it locks. For instructions on adjusting the PA
volume, see “Setting the Gain for Public Address (Microphone Volume)” on page 38.
